The Vatac wafer style resilient seated butterfly valve is designed to maintain a seal against bi-directional pressure differential to prevent backflow in systems designed for unidirectional flow. It accomplishes this with a tightly fitting seal, i.e., gasket, o-ring, precision machined, and a flat valve face on the upstream and downstream sides of the valve.

Vatac Lug-style valves have threaded inserts at both sides of the valve body. This allows them to be installed into a system using two sets of bolts and no nuts. The valve is installed between two flanges using a separate set of bolts for each flange. This setup permits either side of the piping system to be disconnected without disturbing the other side.

Vatac Burried Service Butterfly Valves are manufactured with a 250 psi rating. The valves is capable of operating at pressures of 250 psi and comply with the following details:

» VALVE BODY - Constructed of ductile iron ASTM A-536. End connections shall be ANSI Class 250 with 250# drilling pattern
» VALVE DISC - Made from ductile iron ASTM A-536. Discs shall be furnished with 316 stainless steel seating edge to mate with the rubber seat
» VALVE SEAT - Buna-N rubber located on the valve body
» VALVE SHAFT - Stainless steel ASTM A-564 Type 630 Condition H-1150. Stub shafts or through shafts are acceptable.
» SHAFT SEAL - Standard self-adjusting split "V" type packing. Shaft seals shall be of a design allowing replacement without removing the valve shaft.
» VALVE BEARING - Sleeve type that are corrosion resistant and self-lubricating.
» VALVE ACTUATOR - Fully grease packed and have stops in the open/closed position. The actuator has a mechanical stop which will withstand an input torque of 450 ft/lbs. against the stop. The traveling nut engages alignment grooves in the housing. The actuators has a built in packing leak bypass to eliminate possible leakage into the actuator housing.

All Valves are hydrostatic and leak tested before ex-work. The leak test will be performed at a differential pressure of 250 psi with the disc in a closed position. In a slightly open position, internal hydrostatic pressure equal to 500 psi is applied to the inside of the valve body for five minutes.

The Vatac Turbine Inlet Hydraulic Counterweight Butterfly Valve is one of the updated product which is installed at the inlet of the turbine; it is widely used as an out valve in irrigation works, power stations and various pump stations, replacing non-return valve and gate valve.  While working, the valve cooperates with host computer of the pipeline, according to the transition course principle of water conservancy, through the procedure of opening and closing that is preserved, dispel the pipeline water hammer effectively, realize the ending reliably of the pipeline, and play a role in protecting systematic security of pipeline.

MAIN FEATURES AND ADVANTAGES:
» Multi-functional electro-hydraulic control system, can be debugged, site control as an independent systematic unit without any outside forces.
» Perfect controllability and wide regulation range / adaptability.
» Main valve Sealing Part is made of a triple-eccentric metal sealing or double-eccentric rubber sealing structure.
» Low Torque operation
» Extra enlarge eccentric which ensure an automatic closing and sealing performance

» Size Ranges: DN300 to DN 2000
» Pressure Classes: PN6 / 10 / 16, ASME #125, #150
